ABSTRACT We compared the seroprevalence of SARS-CoV-2 anti-nucleocapsid antibodies in blood donors across Canadian regions in 2021. The seroprevalence was the highest in Alberta and the Prairies. and it was so low in Atlantic Canada that few correlates were observed. Being male and of young age were predictive of seropositivity. https://thegreensjunglebeautyshops.shop/product-category/book/
